The KISD detectors are indium antimonide (InSb) photodiodes available with or without integral high frequency amplifiers. Detector sizes are 0.5 mm,

1.0 mm, and 2.0 mm. The standard package is a side-looking Dewar with SMA connectors and a sapphire window.

KISD (without amplifiers)

KISD photodiodes are designed for moderate electrical bandwidth with maximum detectivity. The bandwidth is limited only by detector size, which determines RC time constant. A 1.0 mm size detector has 25 ns rise time. Peak

responsivity is greater than 2 Amp/Watt and D*(peak, 10kHz, 60FOV) is greater than 1x1011 Jones.

KISDP (with amplifiers)

The photodiode is integrated with high frequency (DC to 20 MHz) amplifiers.
